COP-BUILDING MECHANISM FOR SPINNING AND DOUBLING MACHINERY.

SPECIFICATION forming part of Letters Patent N 0. 691,991, dated January28, 1 902.

I Application filed April 12, 1901. Serial No. 55,514. (No modelJ T0ctZZ whom it may concern.-

Be it known thatI,THOMAS WATSON, a subject of the King of GreatBritainand Ireland, and a resident of Bridge of YVeir, in the county ofRenfrew, Scotland, (whose postal address is Glenapp, Bridge of Weir,Scotland have invented certain Improved Cop Building Mechanism forSpinning and Doubling Machinery, (for which application for Britishpatent has been made, N0.16,816, dated September 21, 1900,) of which thefollowing is a specification.

This invention has for its object to provide improved cop-buildingmechanism for spinning and doubling machinery whereby the yarn is wound011 the spindle more closely and firmly than by present existing means.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2is a transverse section, of a spinning-frame provided with theherein-described improvement. Fig. 3 is a side elevation, and Fig. 4 isa front elevation, of change-levers used in the improved mechanism.Figs. 5, 6, and 7 are respectively a front elevation, a plan, and a sideelevation, of a stop-frame which acts in conjunction with thechange-levers. Fig. 8 is a view showing the wound cop.

As shown in the drawings, fliers 1, having grooved pulleys, are mountedon the station ary rail 4 and surround the spindles 3. These fiiers maybe of ordinary construction and may be driven by ropes from the drums 13and 14. For the sake of clearness I have not shown I these ropes, whichare not essential, the hereinafter-described invention pertaining to thespindle and its operating mechanism.

The spindle is arranged to move up and down during the winding, so as tobuild the cop, a regular upward-and-downward movement being imparted tothe movable rail 29, which works in guides 42, formed on the framing,the stroke of the rail being gradually reduced in order to build the copwith the requisite taper at the ends. The mechanism for moving thebuilding-rail 29 is as follows: A vertical shaft 43, Figs. 1 and 2, ismounted on the framing and is driven from the main shaft 44, preferablythrough spur-and-worm and worm-Wheel gearing 45, as shown. The verticalshaft 43 has on its lower enda bevelpinion 46, which gears at one timewith one of a pair of bevel-pinions 47 48, formed on a piece 49, fittedto slide on a cross-shaft 50, the inner end of the pinion-piece beingformed with clutch-jaws 51, which fit corresponding projections 52 on aclutch-piece53, fixed to the shaft. The pinion-piece 49 may, however, beconnected to the shaft in any other convenient way. The cross-shaft 50has fixed to it a worm 54, gearing with a worm-wheel 55, fixed to ashaft 56, mounted longitudinally on the framing, this shaft having fixedto it a winding drum or barrel 57 (shown in Figs. 1 and 2) for impartingmovement to the building-rail 29. The winding-drum 57 is suitablyconnected, preferably by adjustable chains 58, to similar drums 59 60,fixed to shafts 61 62, mounted longitudinally on the framing on eachside of the machine, the connection to the building-rail 29 beingfinally formed by other drums 63 64, fixed to the side shafts, thesedrums being also connected by chains 65 66 to studs 67 68, fixed to therail, the drums 63 imparting the upward movement to the rail and thedrums 64 the downward movement. The direction of movement up ordownofthe building-rail 29 depends upon which of the crossshaft pinions 4748 is in gear with the verticalshaft pinion 46, the cross-shaft pinionsbeing made to gear in turn with the vertical-shaft pinion by thefollowing automatic arrangement: A two-armed lever 69, Figs. 3 and 4, ismounted vertically on a stud 7 0 on the framing and has its lower endformed with a fork 71, which engages with the pinion-piece 49 on thecross-shaft 50. The upperarm 72 of this change-lever 69 has fixed to ita tappet 73, which engages in a slot 74, formed through the arm 75 of abell-crank lever 76, pivoted on a stud 77 on the framing and acting infront of the change-lever 69, a clearance-opening 78 being formedthrough this latter lever 69 for the stud to pass through and to permitthe lever to travel. The tappet 73 in itsnormal position bears againstone endof the slot 74, as shown in Fig. 4. An extra or auxiliary tappet79 is provided on the upper arm of the change-lever 69, this tappetengaging in a square-shaped slot 80, formed through the arm of thebell-crank. A shifting bolt or pusher 81 is arranged to move up and downon guides in the change-leverframe-piece 82. The guides consist of studs83, which are screwed into the frame 82, the heads 84 of the studsprojecting through slots 85in the pusher 81, and thereby constitutingthe guide parts. The lower end 86 of the pusher 81 is V-shaped and actson a similarly-shaped part 87, formed on the end of the upper arm of thebellcrank 76. The pusher 81 is controlled by a spring 88, the upper endof the spring being attached to the pusher and the lower end to theframe-piece 82. A locking device for the change-lever tappet 73 isprovided in connection with the pusher 81, the locking-piece 89 beingarranged to move up and down on the outer ends of the pusher-guides 84,these outer ends engaging in slots 90, formed through the locking-piece89,which is kept on the guides by pin-and-washer attachments 91. Thelower end ofthelocking-pieceis formedwithatoe 92, which is arranged tofall in front of the upper tappet 73 on the change-lever 69, so asthereby to lock the lever in the proper position. The toe is raisedclear of the tappet 73 at the proper time by the pusher 81, a pin 93,fixed to the pusher, acting on the upper end of a slot 94, formedthrough the locking-piece 89. A stop or catch 95, controlled bya spring96, is provided to act on the pointed end 97 of the upper arm of thechange-lever 69, the pointed end engaging in turn in two suitableindentations 98 99, formed on the under side of the catch 95. The otherarm 100 of the bell-crank 76 extends inward, occupying normallyapartly-horizontal position and having on its outer end a tappet 101,arranged to be acted on by stops 102 103, which are preferably of acushion-type. Each stop is fitted to work in an adjustable socket 104,one end of the stop being formed with a head 105, and the other endpassing through the socket and provided with a retaining pin or catch106.

The cushioning device consists of a spring 107, which is arranged withinthe socket 104, so as to act between a shoulder 108 on the stop and theinner end 109 of the socket. This cushioning arrangement prevents anyjarring action when the tappet 101 comes in contact with the stops. Thesockets 104 for the stops 102 103 are screwed into nut-pieces 110 11],working, respectively, on the upper and lower portions of a spindle 112,mounted in a frame 113, Figs. 5, 6, and 7, formed with a flange orbracket 114, by means of which it is fixed to the movable or buildingrail 29, the upper screwed part of the spindle having preferably aright-hand thread and the lower screwed part 116 a left-hand thread, thespindle being fitted in the frame so that it cannot move endwise. At thecommencement of the winding the stop-nuts 110 111 are placed at thedesired positions on the vertical screwed spindle 112 by means of anadjusting-handle 117, fixed to a ratchet-wheel 118, fixed to the upperend of the spindle. In the drawings the building-rail 29 on one side ofthe machine only is shown, the rail being shown on its upward stroke andset at about half-stroke. The building-rail on the other side of themachine is similarly set and is on its downward stroke. When theupwardmoving rail 29 reaches to nearly the end of its stroke, thelowercushion-stop 103 acts against the tappet 101, on the bell-crank lever76, so as thereby to turn the lever and cause the other or inner end ofthe slot 74 in the vertical arm 75 of the bell-crank to bear against theupper tappet 73 in the change-lever 69. Just immediately before the endof the slot 74 reaches the upper tappet 73 the auxiliary tappet 79 isacted on by the bell-crank, so as to imparta slight starting movement tothe change-lever. During this first movement of the bell-crank 76 oneside 119 of its V-shaped upper end acts against the corresponding side120 on the lower end of the pusher 81, so as thereby to raise the pusheragainst the action of the spring 88. The locking-toe 92 is also raisedshortly afterward along with the pusher, so as to clear the upper tappet73, the vertical arm 75 of the bell-crank traveling far enough around,so as to cause the corresponding opposite V-shaped parts 121 122 on thepusher and bell-crank just to begin to come in contact with each other.The pusherspring 88 then acts so as to force down the pusher 81 againstthe vertical arm 75 of the bell-crank. The \l-shaped side 121 of thepusher 81 is thus pressed down against the corresponding part 122 of thevertical arm 75 of the bellcrank 76, so that the bell-crank lever isturned still farther around. This second movement of the bell-crank 76produces a turning movement of the change-lever 69 by reason of the endof the slot 74 in the vertical arm of the bell-crank bearing against theupper tappet of the change-lever. The change-lever 69, which isconnected to the cross-shaft pinions 47 48, is thus turned so as toplace the inner cross-shaft pinion 48 out of gear and the outer one 47in gear with the vertical-shaft pinion 46, thereby changing thedirection of the movement of the buildingrails. When the movements ofthe bell-crank and change-lever are completed, the lockingtoe 92 hasfallen in front of the other side of the upper tappet 73 of thechange-lever 69, and the pointed end 97 of the lever engages in theother indentation 98 in the spring-stop 95, so that the change-lever isby this means firmly locked in position until another action of theparts takes place. The bell-crank lever 76 is also held in positionuntil another action of the parts by the V-shaped end of the pusher 81pressing against the end of the vertical arm 75 of the bell-crank. Asimilar action of the parts takes place during the opposite movementsofthe building-rails.

The stroke of the building-rails is reduced in the following way: Atappet-lever 123 is arranged to turn loosely on the upper end of thescrewed spindle 112 in the stop-frame 113. The tappet-lever 123 hasfitted to its upper side a pawl 124, which is pivoted on a pin 125 andengages with the teeth on the ratchet-wheel 118, fixed to the spindle112, a spring-piece 126 being provided to act on the outer end or bosspart 127 of the pawl, so as TIO to keep it always in contact with thewheel. During each stroke of the building-rails 29 the tappet-lever 123encounters an inwardlyprojecting cam-piece 160, Fig. 2, fixed to theupper fixed rail 4, so that the tappet-lever is thereby turned inward,so as to move the pawl 124 and turn the ratchet-wheel118 and screwedspindle 112. This movement of the screwed spindle 112 causes thenut-stops 102 103 to approach each other, thus causing them to actsooner on the bell-crank lever 7 6, and thereby eifectin g the necessaryreduction in the stroke of the building-rails 29. An adjusting-pin 128,working in a bracket 129, is provided for adjusting or reducing thepositive turning movement of the tappet-lever 123, so as thereby toadjust or reduce the movement of the nut-stops 102 103 when desired. Thetappet-lever 123 when not in action is always in contact with the end ofthe adjusting-pin 128, being held in this position by the action of aspring 130, having its inner end fixed to the tappet-lever and its outerend to the side of the bracket in which the adjusting-pin works.
